Init Application Response Time SYN SYN/ACK ACK Server Response Time Request Datas ACK RTT OUT (WAN) Datas ACK RTT IN (LAN) Request ACK Network application performance monitoring is governed by two drivers: the calculation layer of the network performance metrics and the network object inspection depth and granularity. H5 choice was to extensively develop the Layer 4 and strongly rely on IETF standards (TCP, UDP, RTP, etc.) accepted and used by all the industry. The metrics calculated by all H5 appliances allows administrators to set efficient and application aware performance troubleshooting strategies without the risk of depending on proprietary technologies. Besides H5 choice for inspection depth was to identify the network nodes by their IP addresses and VLANs and record and aggregate 100% of top conversations on the network with no information loss usually due to deeper and less reliable network session technologies. These two choices allowed H5 to design strong and reliable solution that enable in one single appliance real time network application trouble shooting and latter stage analyses of network events and conditions weeks and months they occurred. In addition to being exhaustive and reliable advanced Layer 4 monitoring provides network application data that network managers can easily correlate with business application user experience and behavior and network infrastructure operating state. Application performance With more than 50 TCP and UDP metrics recording application performance and transmission conditions over the network H5 Appliances provide network operation engineers with the most efficient and reliable user quality of experience and behavior information. More than any other metrics TCP server response time and TCP round trip time peaks allows network operation engineers to isolate abnormal conditions and degraded performance situation over time and in the cloud of conversations. Most of the metrics are either server or client side (or in some conditions LAN or WAN side) to enable infrastructure trouble shooting. P6 P5 Data aggregation over time Network AƉƉůŝĐĂƟŽŶ Flows 1-Minute Data 5-Minutes Data 1-Hour Data 1-Day Data All top conversations metrics are stored in a database for quick access. The persistence of the information over large time periods is guaranteed by a robust and intelligent aggregation process that reduces the time granularity while maintaining the conversation records. Network operation engineers can access to the full top conversation metrics months after and can easily compare application behavior and performance for different period of time. P2 P1 P4 ? VoIP quality VoIP voice transfer relies on connectionless RTP (Real Time Protocol) slightly different than TCP. H5 Appliances produce a specific set of metrics for each voice call including well-known MOS allowing network operations engineers to measure the quality of VoIP service without having to deploy complex and costly VoIP agents on phones and gateway. P3 Loss Jitter MOS Watched Object and Business Flows By default all nodes have an equal weight in the H5 appliance conversation database, in order to build network application performance visibility that reflects the network architecture or the corporate organization. H5 Appliance provide several powerful and easy to use features that allow network operation engineers and administrators to arrange and organize flow data and classify custom applications. With Watched Objects network administrators can create or import their network address plan to group IP nodes and process application performance metrics for corporate sites, branches offices, server farms, etc. but also isolate and highlight low volume conversations that would be TCP UDP lost in the conversation cloud. With Business flows, in conjunction or not with watched objects, network managers can classify their custom and business applications and track them specifically over time. Both watched object and business flows allows corporation to align their views, reports and alerts with their business activity and objectves. © 2013 H5 audits - All rights reserved Enhanced IT Team Collaboration H5 Appliance: one-box-to-serve-them-all The H5 appliance provides all the IT teams with the all services in a The services provided by H5 Appliance are tightly integrated and single box for analysis, reporting and abnormal situation make the collaboration between the different IT team more awareness without any third-party software or service: The efficient. For instance, network operation engineers can generate, real-time Java interface H5-Dock for the network operations within a trouble shooting or flow analyzes work session, reports or alerts for the same context he is working center; the web dynamic reporting Network AƉƉůŝĐĂƟŽŶ Flows on with one click.The reporting portal portal for network managers and the showing scheduled or historic reports is SNMP or e-mail alerts for the help constantly fed and updated with the desk. same data as the network operation team. ? Network Engineer HelpDesk Network Application Health Profiling DSI Critical Condition Awareness Real Time Network Analyses H5-Dock: powerful Java client for real-time flow analysis The H5 appliance provides in-one-box all services for all the IT teams without any third-party software or service. The real-time Java interface H5-Dock is the standard graphical user interface provided by the H5 Appliance to network operations engineers. It is downloaded from the H5 Appliance Web interface and run on any workstation using WebStart standard. H5-Dock loads data in real-time from the appliance network application flow database and dynamically displays the node and metrics information on pre defined and custom tables and charts views. Multiple views can be created on a single H5-Dock instance to observe the network flows over different time periods and geographic regions and multiple appliances. The H5-Dock GUI provides a powerful set of analyzes tools including the ability to drill down successively from table views to time chart view to quickly isolate detailed data on specific or abnormal network conditions over a large period and thousands of IT conversations. The network operations engineers can easily design troubleshooting scenario that can be saved loaded and shared within a few clicks. The typical abnormal situations and network application incidents observed on a daily basis contribute therefore to build a knowledge base of troubleshooting conditions that gradually improve the productivity of the network operations center and reduce the network application incidents downtime. H5 Appliance: Aggregation objects The key feature for forensics and drilldown strategies with H5 Appliances are the aggregation objects. When visualizing the network conversation network operations engineers always starts with highest aggregation objects to get the most global picture of the network situation and drilldown to individual nodes and conversation for more detailed views to qualify incidents and Total Traffic Global traffic captured by the appliance. behavior.

H5 Appliance: Scalability and flexibility. H5 Appliances scale as your network and you need for network application visibility grows. The unique H5 Appliance software is supported by the whole range of H5 Appliance hardware platforms. The H5 Appliance model choice only depends on the throughput of traffic that needs to be monitored from a few megabits per second to 10 Gigabits per second. AMoreover, H5 Appliance VLAN support allows the network administrator to take advantage of advanced features provided by high-end network taps such as policy based traffic tagging. For instance a single H5-700 appliance can monitor the traffic of multiple 1Gbps networks over one single 10Gbps monitor interface with full separation of traffic.
